... Name connection This pin is connected to a storage capacitor. A high-voltage regulator connected between pin and this pin provides the supply voltage to the FSQ500N at startup and when switching STR during normal operation. The FSQ500N eliminates the need for auxiliary bias winding and associated external components. ...
